LibriFSD50K (LFSD): This dataset consists of a diverse set of speakers drawn from the LibriSpeech [1]} corpus and a wide variety of background noises from FSD50K [2]}. Specifically, \(45{,}602\)  and \(3{,}081\)  for training and validation, correspondingly. We follow the same data generation procedure as indicated in [3]}. In this study, this dataset is mainly used for the OOD unsupervised or semi-supervised pre-training of speech enhancement models.
